Original abstract

Thermal conductance measurement in the simulated deep space and Martian atmosphere conditions is one of the key objectives in the Miniaturized Heat Switch redesign and development project. The experiments are to be performed in the thermo-vacuum test chamber, once the measurement interference and accuracy are determined. For this purpose, calibration specimens were manufactured and tested. The tests were performed under 10(-3) Pa pressure, according to the qualification requirements. The data were used to design test apparatus's thermal model, capable of specimens thermal conductance evaluation. The thermal model results identified potential refinement parameters. The model applicability should be verified once a sufficient amount of data is evaluated.
